VEHICLE SIGNAL.

Application med september 29, 19211.

To all whom t may concern:

Be it known that I, DANGELO MAURO, a subject of the King of Italy and resident of San Jose, in the county of anta Clara and State of California, have invented certain new and useful Improvements in Vehicle Signals, of which the following is a specification.

It is the object of my invention to provide a simple, positively acting, and efficient.

device for indicating the direction in which a vehicle is about to turn or indicating that the vehicle is about to stop as the case may be.

It is a further object of my invention to provide a device of the character indicated that is equipped with means whereby the same is automatically illuminated in the right, left and stop positions.

In the drawings,-

Figure 1 is a side elevation of the device in an operative position.

Figure 2 is a plan view of the same.

Figure 3 is an enlarged side elevation of the indicator end of the signal.

Figure 4 is a section on line 4 4 of Figure 2.

Figure 5 is a diagram of the electrical lighting circuit.

4Referring more particularly to the drawing, 1 indicates a portion of the automobile to which the signal is attached, and 2 a clamp used for effecting such attachment.

Clamp 2 carries a pair of ears 3-3 upon which is mounted a hollow metal arrow 4 by means of a pin or pivot 5, the pivotal connection being made to the upper edge of the arrow shaft. In the present case an orice 6 is formed in the clamp 2 and provided with a stop 7 as Shown. An arm 8 is extended through orifice 6 and provided with a handle 9 and connected to the upper edge of the arrow shaft as at 10 by means of a link 11. Notches 12 are formed in arm 8 to engage stop and maintain the arrow in a required position as at 13, 14 or 15.

The head 16 of the arrow 4 is formed as a hollow box having a cover 17 slidably mounted thereon, and Fitted with red glass windows as at 18 and 19.

Mounted in head 16 is an electric light bulb 20 arranged in an electrical circuit as 21. In circuit 21 is arranged a stationary plate 22 mounted on bracket 2 near the base of arrow 4. Mounted on the base of arrow 4f and in the same electrical circuit is a serial No: 504,172.

spring element 23, the same being so arranged and proportioned as to break contact with plate 22 when the arrow is in a vertical position, but to contact with the plate and thereby close the electrical circuit when the. arrow is in an operative position as indicated at let-Q-Q When the device is properly constructed and mounted upon frame 1, the arrow is held in a vertical and inoperative position by the engagement of one notch 12 in rod 8 with stop 7. If it is the intention of the driverto stop he merely knocks arm 8 loose from engagement with stop' 7 whereupon the arrow falls into its lowest position as 25 and is automatically illuminated through the closing of the electrical circuit at 22--23. If it` is only desired to give the turn right or turn left signal, then the arm 8 is kept under lcontrol and the arrow permitted to drop only until the desired notch engages stop 7.

A stop is also formed in support 2 as at 26 whereby the arrow may be dropped to position 25 and held without the use of a notch 12, this construction permitting the quick dropping of the arm to the stop position.

It may thus be seen that I have provided a device that is simple in construction and operation, economical to manufacture, positive in action and highly eiiicient in its pracc tical application.

It is to be understood, of course, that changes in construction and method of operation may be made within the scope of the appended claims.

I claim:

1. A vehicle signal comprising a support having a stop formed thereon, an indicator arm pivotally mounted thereon to move in a vertical plane, an actuating bar pivotallv connected to said arm adjacentr the pivotal end thereof, and having spaced notches formed therein to engage said stop.

2. A vehicle signal comprising a support.'

having a pair of stops formed therein, an indica-tor arm pivotally mounted thereon to move in a vertical plane. an actuating bar pivotally connected to said arm adjacent the pivotal end thereof and having spaced notches formed therein to engage one of said stops to support said arm in either one of two operative positions, said arm being supported in the third operative position by the second stop of said pair.

3. A vehicle signal comprising a support having an orifice formed therein, a stop arranged in said orifice, an indicator arni pivotally mounted on said support to move in a vertical plane, an actuating bar pivotally connected to said arm and passing through said orifice and provided with spaced means for engaging said stop.

4. A vehicle signal comprising a support having a pair of vertically spaced stops formed therein, an indicator arm pivotally mounted thereon to move in a vertical plane, actuating means connected to said arm and engageable With the upper stop to support Said arm in either of two operative positions, the said arm being formed to engage the lower stop for supporting it in a third operative position.

DANGELO MAURO.
